Abstract

A method of fabricating a semiconductor structure includes the formation of a first bonding layer at least substantially comprised of a first III-V material on a major surface of a first element, and formation of a second bonding layer at least substantially comprised of a second III-V material on a major surface of a second element. The first bonding layer and the second bonding layer are disposed between the first element and the second element, and the first element and the second element are attached to one another at a bonding interface disposed between the first bonding layer and the second bonding layer. Semiconductor structures are fabricated using such methods.
